OZRO O. HEATH, OF PROVIDENCE, RHODE ISLAND.

AUTOlVlATlC FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 266,142, dated October17, 1882.

(No model.)

To all whom tt may concern Beit known that I, Ozao G. HEATH, a citizenof the United States, residing at Providence, in the county ofProvidence and State of Rhode Island, have invented certain new anduset'ul Improvements in Automatic Fire- Extinguishers; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in' automatic fire-extinguishers,the object ot' which is, first, to remove the low-fusible material fromwater contact, so as to insure the prompt and eflicient working ot'theextinguisher; secondly, to permit the valve to be removed by hand fromits seat without damaging the fusible solderjoint, and, lastly, tosecure a thorough distribution ot' the duid-supply as well immediatelybelow the extinguisher as outwardly from it.

To these ends my invention consists ot' the parts substantially ashereinafter described, and particularly pointed out in the claims.

In the annexed drawings, Figure l is a front elevation ot' my improvedautomatic lire-extinguisher. Fig. 2 is a side elevation thereof'. Fig. 3is a` longitudinal vertical section online a' as of Fig. 2. Fig'. 1Jc isa similar view, with the exception that the valve, its stem, and theseal are shown in the position assumed upon the melting ofthe fusiblesolder; and Fig. 5 is a transverse section ou line y y of Fig. 1,exhibiting a plan ot' the distributer and valve.

Corresponding parts in the several figures are indicated by similarletters ot'refcrence.

Rei'erringto the drawings, Amarks the base, provided with the usualscrew-threaded portion, a, and nozzle B, which is provided at its outeror lower edge with a valve-seat, b. Oast in one piece with the base, anddepending on opposite sides therefrom, are two arms, O,whose ends arecurved ,toward each other, and are joined to or east with the annulusc.Secured to and within the arms O, between said annulus c and base A, isthe distributerD, formed of a tiat bottom with an upturned annular rimor wall, which is disposed at right angles to said bottom, and isprovided with the serrated edge,

as shown, and a number ot' slits, d, extending down the rim or wall andpartially across the valve stem F, and held-against the valve-seat bbymeans ofthe screw-threaded seal Gr, which receives the screw-threadedend of the valvestem F, and is held in the annulus c with lowfusiblematerial. rIhe lower end ot' the valvestem F is provided with a nick, topermit the stem to ne screwed up to press the valve E against its seatb. It will be noticed that the valve-stein passes through a centralopening in the distributer.

Several openings, H, may be made in the arms O to serve as fluid-exits,so that no break will ocourin the distribution ot' the fluid-supply byreason ot' said arms C.

The normal position of parts is shown in Figs. 1, 2, and 3.

Upon the occasion of a tire the heat will melt the low-fusible solderwith which seal Gr is secured to annulus c, whereupon thc valve E willl'all 't'roin its seat l) and rest on the bottom ot' the distributer,asshown in Figs. 4 and 5, when it performs the office of a detlector todirect the tluid-snpply through the slits and the serrated edge.

It will-bc noticed from the foregoing that the valve can be removed fromits seat either automatically or by hand; that leakage can be promptlydetected and the valve tightened that the duid-supply will bedistributed below the extinguisher, as well as outwardly from it, tliusovercoming an objection incidentto many existing extinguishers, and thatthe valve acts to prevent the escape ot' fluid-supply until the occasionot' a lire, when it then serves as a detlector to secure a betterdistribution of the llud-suppl v.

Having thus describedmy invention, what I 9 claim, and desire to secureby Letters Patent, is

l. In an automaticlire-extinguisher,thecombination, with the baseprovided with a nozzle, ofthe pendent distributer having the serratedIOO edge, and the slits extending down the rim und partially neross thebottom of the distribnter, and the conical valve with its stem,substantially as shown and described.

2. rlhe combination, substantially as before set forth7 of the baseprovided with n nozzle and valve-sent, the frame secured to the buse andprovided with the nnnnlns, und ai distributer arranged between sind busennd :nr nnlus, the valve with its scre\\'thre.f1dcd valve- Stem, and thescrewthreaded hard-metal nut secured with low-fusible material to the:1nnnlns.

3. rlhe base provided with :inozzle und valvesea-t, the frame secured tothe base :1nd provided with the annnlns, the distribnter nttnched t0 thefrmnebctwcen said base andannulus,and having; the upturncd rim with itsserrated odge, and the slits extending down the rim :ind partiallyacross the bottom of said distribnter, the valve with its screwthrendedstem, and the screwthrended hnrd-metnl nut scoured With low-fusiblematerial to the annulns, in combination, substantially as shown anddescribed.

In testimony whereof I. :ltix my signature in presence ot' twoWitnesses.
